The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."

The technique is based on the late 19th century sensitometry studies of Hurter and Driffield. The Zone System provides photographers with a systematic method of precisely defining the relationship between the way they visualize the photographic subject and the final results. Although it originated with black-and-white sheet film, the Zone System is also applicable to roll film, both black-and-white and color, negative and reversal, and to digital photography.

🔗 Computing 🔗 Computing/Software

The Pick operating system (often called just "the Pick system" or simply "Pick") is a demand-paged, multiuser, virtual memory, time-sharing computer operating system based around a unique MultiValue database. Pick is used primarily for business data processing. It is named after one of its developers, Dick Pick.

The term "Pick system" has also come to be used as the general name of all operating environments which employ this multivalued database and have some implementation of Pick/BASIC and ENGLISH/Access queries. Although Pick started on a variety of minicomputers, the system and its various implementations eventually spread to a large assortment of microcomputers, personal computers and mainframe computers.

🔗 Computing

Excess-3, 3-excess or 10-excess-3 binary code (often abbreviated as XS-3, 3XS or X3), shifted binary or Stibitz code (after George Stibitz, who built a relay-based adding machine in 1937) is a self-complementary binary-coded decimal (BCD) code and numeral system. It is a biased representation. Excess-3 code was used on some older computers as well as in cash registers and hand-held portable electronic calculators of the 1970s, among other uses.

🔗 Ukraine 🔗 Cities

New York or Niu-York is a rural settlement in Toretsk urban hromada, Bakhmut Raion, Donetsk Oblast, eastern Ukraine. It is located 37.9 kilometres (23.5 mi) north-northeast from the centre of the city of Donetsk. From 1951 to 2021, the settlement was named Novhorodske.

New York is administratively designated to Toretsk urban hromada, one of the hromadas of Ukraine with its center in the city of Toretsk, that is located about 10 kilometres (6.2 mi) north of New York. Population: 9,735 (2022 estimate).

🔗 California 🔗 LGBT studies

Stonewall Nation was the informal name given to a proposition by gay activists to establish a separatist community in Alpine County, California in 1970. The small population of the county and the election rules for California counties at the time suggested to these activists that if they could induce a relatively small number of gay people to move to the county, they could recall the county government and replace it with an all-gay slate.

The plan did not gain traction in the LGBT community and a right-wing Christian minister announced plans to move large numbers of Christians to the county to counteract any attempt by gay people to take over the county government. The plan was abandoned about a year after it was conceived and the idea has come to be seen as a practical joke.

🔗 Psychology

In psychology, the Zeigarnik effect occurs when an activity that has been interrupted may be more readily recalled. It postulates that people remember unfinished or interrupted tasks better than completed tasks. In Gestalt psychology, the Zeigarnik effect has been used to demonstrate the general presence of Gestalt phenomena: not just appearing as perceptual effects, but also present in cognition.

The Venetian Arsenal (Italian: Arsenale di Venezia) is a complex of former shipyards and armories clustered together in the city of Venice in northern Italy. Owned by the state, the Arsenal was responsible for the bulk of the Venetian republic's naval power from the late Middle Ages to the early modern period. It was "one of the earliest large-scale industrial enterprises in history".

🔗 Apple Inc.

SWEET16 is an interpreted byte-code instruction set invented by Steve Wozniak and implemented as part of the Integer BASIC ROM in the Apple II series of computers. It was created because Wozniak needed to manipulate 16-bit pointer data, and the Apple II was an 8-bit computer.

SWEET16 was not used by the core BASIC code, but was later used to implement several utilities. Notable among these was the line renumbering routine, which was included in the Programmer's Aid #1 ROM, added to later Apple II models and available for user installation on earlier examples.

SWEET16 code is executed as if it were running on a 16-bit processor with sixteen internal 16-bit little-endian registers, named R0 through R15. Some registers have well-defined functions:

• R0 – accumulator
• R12 – subroutine stack pointer
• R13 – stores the result of all comparison operations for branch testing
• R14 – status register
• R15 – program counter

The 16 virtual registers, 32 bytes in total, are located in the zero page of the Apple II's real, physical memory map (at $00–$1F), with values stored as low byte followed by high byte. The SWEET16 interpreter itself is located from $F689 to $F7FC in the Integer BASIC ROM.

According to Wozniak, the SWEET16 implementation is a model of frugal coding, taking up only about 300 bytes in memory. SWEET16 runs at about one-tenth the speed of the equivalent native 6502 code.

Wikiracing is a game using the online encyclopedia Wikipedia which focuses on traversing links from one page to another. It has many different variations and names, including The Wikipedia Game, Wikipedia Maze, Wikispeedia, Wikiwars, Wikipedia Ball, and Litner Ball. External websites have been created to facilitate the game.

The Seattle Times has recommended it as a good educational pastime for children and the Larchmont Gazette has said, "While I don't know any teenagers who would curl up with an encyclopedia for a good read, I hear that a lot are reading it in the process of playing the Wikipedia Game".

The Amazing Wiki Race has been an event at the TechOlympics and the Yale Freshman Olympics.

The average number of links separating any Wikipedia page from the United Kingdom page is 3.67. Other common houserules such as not using the United States page increase the difficulty of the game.

As of July 2019, a website and game known as The Wiki Game has been created, allowing players to Wikirace against each other in a server, for more points and recognition on the server. The game reached more recognition as Internet stars such as Game Grumps played it on their channels. There is a version on the App Store as well, in which players can do a variety of Wikirace styles from their phone.
